Bridge Link to Building
Bridge Link to Building
(OP)
Hi,
I have to design a very small reinforced concrete bridge link between a concrete cantilevered concrete footpath and a building.
Typically I try to design these types of structures independent from the structure but in this case the bridge link is only 6-8 feet long. It might look funny to have too many columns.
Because of the length I am planning to keep the bridge link independent at the cantilever supported with one column and attached directly to the building on the other end.
Any thoughts against this?
thanks

Having a space to locate a column for you to have one end rigid and the other end free is wise, and isolating the free end to move in the direction of crossing is also a good option to reduce any rotation on the existing building.

Steel is not an option so I am having a 6" slab supported on a beam/column.
The beam will be cast right up to the cantilever edge. Since there a likely possibility of an undesirable crack, I plan to notch the edge of the cantilever and cast a small portion of the bridge link over the cantilevered slab. My thoughts are that the crack that will develop will be easier to maintain. I am thinking of placing some flexcell on the underside and along the edge of this overlap to help with any deflections/movements.
Any additional thoughts?
Thanks

So I would check the stress at the notched end at the cross section change and i'll make sure I reinforce this area well against shearing stresses.
Good luck.
